複製程式碼 程式碼如下:
header("Content-type: text/html; charset=utf-8");
function multiple_replace_words($word,$replace,$string,$t. '){
preg_match_all('/'.$word.'/',$string,$matches); //符合所有關鍵字
$search = explode(',','/'.implode('/,/ ',$matches[0]).'/');
//不存在匹配關鍵字
if(empty($matches[0])) return false;
//特殊替換設定
$count = count($ matches[0]);
foreach($replace as $key=>$val){
if(!isset($matches[0][$key])) unset($replace[$key]); //剔除越界替換
}
//合併特殊替換數組與匹配數組
for($i=0;$i$matches[0][$i] = isset($replace[$i ])? $replace[$i] : $matches[0][$i];
}
$replace = $matches[0];
//防止替換循環,也就是替換字符仍是被替換字符,此時將其暫時替換一個特定字元$tmp_match
$replace = implode(',',$replace);
$replace = str_replace($replace = implode(',',$replace);
$replace = str_replace($word,$tmp_match,$replace); //暫時替換匹配字元
$replace = explode(',',$replace);
//替換處理
$string = preg_replace($search,$replace,$string,1); //每次只替換數組中的一個
$string = str_replace($ tmp_match,$word,$string); //還原暫時替換的匹配字元
return $string;
}
//範例1
$string = 'aaabaaacaaadaaa'; re
$word = 'aaa'; (null,'xxx','yyy');
echo '原文:'.$string.'
輸出:'.multiple_replace_words($word,$replace,$string).'
';
//例2
$string = '中文aaab中文ccaaad中文eee';
$word = '中文';
$replace = array(null,'(替換中文2)','(取代中文2)','(代入中文3)');
echo '原文:'.$string.'
輸出:'.multiple_replace_words($word,$replace,$string);
/*
輸出結果:
aaabaaabaaacaaadao🠟帶輸出: aaabxxxcyyydaaa
原文:中文aaab中文ccaaad中文eee
輸出:中文aaab(替換中文2)ccaaad(替換中文3)eee
